[Power Supply Design Proposal Case] Cost Optimization through Overhauling Obsolete Components

[Power Supply Design Proposal Case] Cost Optimization through Overhauling Obsolete Components

Only replace items with a limited lifespan, such as electrolytic capacitors! An example of compatibility with power supplies manufactured several decades ago!

We received a request from a customer using a power supply unit manufactured several decades ago, asking for repairs due to a malfunction. Many of the components are discontinued, and the manufacturer has also ceased support, which is why they consulted us. While there was an option to replace it with a new power supply unit, they were planning to replace the entire equipment soon, so we proposed an overhaul that would only involve replacing the electrolytic capacitors and other components with a limited lifespan. [Issues] ■ The power supply unit manufactured several decades ago has malfunctioned and needs repair. ■ Many of the components are discontinued. ■ The manufacturer's support has also ended. *For more details, please refer to the related link page or feel free to contact us.

15 Examples of Causes and Countermeasures for Capacitor Failures (with Diagrams)

15 Examples of Causes and Countermeasures for Capacitor Failures (with Diagrams)

To ensure that our capacitors are used with higher reliability, we would like to introduce some examples of troubles.

When a capacitor fails, electronic devices may not operate as expected, potentially leading to unexpected accidents. However, it is impossible to eliminate capacitor failures entirely. Therefore, our company, which has been manufacturing capacitors for about 70 years, will introduce the causes of failures and examples of countermeasures to ensure that capacitors are used appropriately and safely. [Failure Phenomena and Examples, Causes and Countermeasures] ■ Smoke emitted from a capacitor that shorted due to overvoltage ■ A capacitor failed due to excessive ripple, causing electrolyte to spray out ■ A capacitor in the charge and discharge circuit lost its capacitance ■ A pressure valve failed to operate, causing steam to erupt from the grounding surface ■ One of the capacitors connected in parallel failed ■ The characteristics of an aluminum electrolytic capacitor decreased at low temperatures ■ The characteristics of an aluminum electrolytic capacitor deteriorated after long-term storage ■ An aluminum electrolytic capacitor sparked ■ An aluminum electrolytic capacitor installed horizontally burst ■ An aluminum electrolytic capacitor connected in series shorted ■ A film capacitor intended for DC use failed when used in an AC circuit ■ A resin-coated film capacitor ignited *For more details, please refer to the PDF document or feel free to contact us.

Introduction to Capacitors That You Can't Ask About Now

For young circuit design engineers! It covers everything from the basics of capacitors to the currently popular large-capacity capacitors.

A capacitor is one of the fundamental and important components in electronic circuits. For engineers involved in circuit design, accurately acquiring knowledge about the characteristics and properties of capacitors is essential for product development. However, when reconsidering the basic operation and mechanisms of capacitors, one might realize that there are oversights and misunderstandings. We will provide an "Introduction to Capacitors You Can No Longer Ask About," covering everything from the basic structure, mechanisms, and design of capacitors to the units used to express the size of capacitors, including the currently popular large-capacity capacitors. *For more details, please refer to the PDF materials or feel free to contact us.*

Causes and Countermeasures for Capacitor Failure: Short Circuit Failure

Causes and Countermeasures for Capacitor Failure: Short Circuit Failure

Explanation of failure modes and factors! There is also a risk of ignition due to reactions with oxygen in the air.

When a capacitor experiences a short circuit failure, it can no longer easily accumulate charge as current flows through it. For example, if a capacitor connected between the input side and ground to eliminate ripple current or noise shorts, a large current will flow from the input to ground. Causes of short circuit failures include applying voltage beyond the rated value, conducting ripple current, and usage under high temperature or high humidity. Additionally, for polarized capacitors, applying pure AC voltage or reverse voltage can also lead to shorts. Furthermore, because the dielectric of a capacitor is very thin, excessive mechanical stress can damage the dielectric and cause a short. It is important not only to consider electrical factors but also to ensure that the capacitor is not subjected to shocks or vibrations. Our related catalog provides a wealth of information on various failure phenomena and case studies, as well as factors and countermeasures. Please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.*

Explanation of the cause of capacitor failure: Coated capacitor has failed.

Explanation of the cause of capacitor failure: Coated capacitor has failed.

The measure is to not coat the entire circumference of the capacitor with a coating agent or resin!

We would like to introduce a case where electrolyte leaked during use, causing a short circuit in the circuit board and resulting in capacitor failure. The electrolyte in aluminum electrolytic capacitors evaporates during operation, releasing gas into the atmosphere through the sealing rubber gasket. Additionally, aluminum electrolytic capacitors are equipped with pressure relief valves. Therefore, if the capacitor is covered with resin or similar materials, it can hinder the release of gas and the operation of the pressure relief valve. In this case, the coating material blocked the pressure relief valve, impairing its function and causing the sealing part of the capacitor to break, leading to electrolyte leakage. As a result, the circuit board wiring short-circuited, and the capacitor failed. **Countermeasures** - Do not cover the entire circumference of the capacitor with coating agents or resin. - Most of our aluminum electrolytic capacitors can withstand vibration tests with acceleration of up to 10G. *For more details, please refer to the PDF document or feel free to contact us.*

[Explanation of the Causes of Capacitor Failure] Failure of a DC Capacitor in an AC Circuit

[Explanation of the Causes of Capacitor Failure] Failure of a DC Capacitor in an AC Circuit

The rated voltage is set with a margin, taking into account factors such as AC frequency, voltage waveform, voltage fluctuations, and operating temperature!

The film capacitor in the power circuit shorted and caught fire. In this case, a film capacitor with a vapor-deposited electrode designed for DC was used in an AC circuit. The effective value of the AC voltage and the DC rated voltage of the capacitor were almost the same. As a result, a voltage exceeding the rated voltage continued to be applied to the capacitor, leading to a short circuit and fire. [Countermeasures] - Change to a film capacitor suitable for AC - Set the rated voltage of the capacitor with an adequate margin, considering AC frequency, voltage waveform, voltage fluctuations, and operating temperature - If the DC voltage contains an AC component, it is necessary to choose a capacitor with a DC rated voltage higher than the peak voltage *For more details, please refer to the PDF document or feel free to contact us.

Introduction to Capacitors: What You Can't Ask About Capacitors Now

Introduction to Capacitors: What You Can't Ask About Capacitors Now

Both capacitors and capacitors are electronic components that can physically store electric charge!

A capacitor is one of the fundamental and important components in electronic circuits. There is no clear distinction between a capacitor and a condenser; both can physically store electric charge. In English-speaking countries, it is called a capacitor (from "electric capacity = capacity"), but in Japan, it is said to have been referred to as "condenser" (＝condenser) due to its function of compressing (＝condense) electricity.
